World today having several services on Web generates high volume of data around, so much so that one cannot just afford to ignore. These data volumes together usually referred as big data, though look heterogeneous and unrelated at a glance; still, big data carry striking relations among them implicitly as well as explicitly, so that many users across the world may get interested of data patterns being generated at a far end of the world. Thus, there is a need to deliver big data available on cyberspace to users as per their needs. This brings in a notion of big data service. For such service, we here propose a cyber infrastructure that takes user's data request and finds an appropriate data service provider to deliver data. We also propose an approach for SLA: service level agreement specification. SLA for a service is derived from SLAs of data consumer and provider on negotiation. Matching of consumer's SLA to that of a provider SLA and a process of negotiation between these two are illustrated.

“…Metrics to measure granularity, complexity and reuse [15,35,36], performance [5,13] and QoS [28,31] of SOAbased services also rely on design-time data. Most work on operation and optimization has been done on how to handle service level agreements primarily based on design-time data: how to formally describe them [19,34,39,40], technically implement, test and enforce them [4,10,15,17,18,23,25,26,32,33,42,44,45] or how to monitor them [2,20,21]. Contributions available on SLA design deal with isolated approaches: Sauvé et al [38] and Marques et al [27] are in favor of deriving the service level targets directly from the business impact of the given service (i.e.…”

The paradigm of service-oriented architectures (SOA) is by now accepted for application integration and in widespread use. As an underlying key-technology of cloud computing and because of unresolved issues during operation and maintenance it remains a hot topic. SOA encapsulates business functionality in services, combining aspects from both the business and infrastructure level. The reuse of services results in hidden chains of dependencies that affect governance and optimization of service-based systems. To guarantee the cost-effective availability of the whole service-based application landscape, the real criticality of each dependency has to be determined for IT Service Management (ITSM) to act accordingly. We propose the FIT-metric as a tool to characterize the stability of existing service configurations based on three components: functionality, integration and traffic. In this paper we describe the design of FIT and apply it to configurations taken from a production-strength SOA-landscape. A prototype of FIT is currently being implemented at Deutsche Post MAIL.

Abstract-A main challenge for service providers is managing service-level agreements (SLAs) with their customers while satisfying their business objectives, such as maximizing profits. Most current systems fail to consider business objectives and thus to provide a complete SLA management solution. This work proposes an SLA-driven management solution that aims to maximize the provider's profit by reducing resource costs as well as fines owning to SLA violations. Specifically, this work proposes a framework that comprises multiple, configurable control loops and supports automatically adjusting service configurations and resource usage in order to maintain SLAs in the most costeffective way. The framework targets services implemented on top of large-scale distributed infrastructures, such as clouds. Experimental results demonstrate its effectiveness in maintaining SLAs while reducing provider costs.
